IMPROVEMENT IN MACHINES FOR BENDING CARRIAGE POLES.

Specification forming part of Letters Patent No. 165,887, dated July 20,1875; application filed I June 9, 1875.

To all whom it may concern:

Be it known that I, A. G. SNYDER, of Ashtabula, in the county ofAshtabula and State of Ohio, have invented certain new and usefulImprovements in Machines for Bending Carriage- Poles; and Ido herebydeclare that the following is a full, clear, and-exact descriptionthereof, reference being had to the accompanying drawing, and to theletters of reference marked thereon, which form part of thisspecification.

The nature of my invention consists in the construction and arrangementof a machine for bending wagon or carriage poles, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figurelisaplanviewofmymachine. Fig.2 is a side elevation of the same, inposition, while completing the bendin Fig. 3 is a side elevavation,showing the position while making the first bend. Figs. 4:, 5, 6, and 7are detached views of certain parts thereof.

A represents the bench, of suitable dimeusions, provided at its frontend with a windlass, B, of ordinary construction. On the rear portion ofthe bench A, is formed a box, (1, with lid D, and at the rear end ofthis box is a screw, E, operating against a block, a. In front of thebox 0, in the bench A, is made a recess with a cross-bar, b. The frontend of the bench is rounded or beveled as shown by dotted line at c. Grrepresents the former, made of two curves, (1 and d. The outerorfrontcurve, d, has a strap, f, connecting it with a bar, H, formedwith a hook, h, on its rear end to fit over the bar 12. To this bar isalso attached a link, i. The rear curve dhas a strap, f, connecting withan abutment,-k.

The straight stick or pole to be bent is put through the link or ring2', up through the former G, against the abutment k, the rear end of thestick being placed in the box 0, and the lid D closed and fastened byany suitable means. By turning the screw E the pole is then forcedagainst the abutment until it is considered taut in the strap. A wedge,m, is then driven in the link i. on top of the pole, and then a ring, a,is placed over the abutment. This ring it is connected to the Windlassby a chain, 19, and by turning the hand-wheel of the Windlass the end ofthe pole is brought down to the curve d of the former, making theendcurve of the pole. It is then fastened by a hook, s. The ring n is thentaken off, and an open hook, it, is placed under the end of the former,near the abutment. Into this hook, on top of the former, is then applieda lever, I, having a T-shaped head, as shown in Fig. 2, by means ofwhich the curve d of the former is brought down on the pole, making thesecond bend therein.

It will be noticed that during this part of the operation the formermakes a partial revolution. It is then fastened at this end of theformer by another hook, 8. Then the lever is removed, and by lettingoffthe screw E, raising the lid D, and moving the former a trifle backward,it, with the bent pole, can be taken off from the bench.

As many formers as may be desired can be used.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

l. The combination of the box 0 with lid D, screw E, former G with itsattachments, ring a, chainp, and Windlass B, all constructedsubstantially as and for the purposes herein set forth.

2. The combination of the box 0 with lid D, screw E, former Gr with itsattachments, hook t, and lever I, all constructed substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing as my own, I aflix my signaturein presence of two Witnesses.

A. e. SNYDER.
